Green's Function Approach to Model Vibrations of Beams with Spatiotemporally Modulated Properties
Benjamin M. Goldsberry, Andrew N. Norris, Samuel P. Wallen +1
The forced time harmonic response of a spatiotemporally-modulated elastic beam of finite length with light damping is derived using a novel Green's function approach. Closed-form s…

Strongly Nonlinear Wave Propagation in Elasto-plastic Metamaterials: Low-order Dynamic Modeling
Samuel P. Wallen, Michael R. Haberman, Washington DeLima
Nonlinear elastic metamaterials are known to support a variety of dynamic phenomena that enhance our capacity to manipulate elastic waves. Since these properties stem from complex,…
